Embodiment 1

[0058] This embodiment provides a method for establishing an EPC bearer, using a mobility management entity (MME) as the execution subject, such as figure 1 As shown, the method includes:

[0059] Step S101, receiving attachment information sent by an Internet of Things terminal.

[0060] When the Internet of Things terminal starts to attach, it sends attachment information to the MME. The attachment information includes: type information of the Internet of Things terminal and power saving mode parameters; wherein, the type information of the Internet of Things terminal is used to represent the type of the Internet of Things terminal, Specifically, it includes fixed-position IoT terminals and mobile-position IoT terminals; the power-saving mode parameter includes the active duration of the IoT terminal, which refers to the duration of a single communication activity of the IoT terminal in the power-saving mode.

[0061] Step S102 , judging whether the Internet of Things termi...

Embodiment 2

[0071] This embodiment provides a method for establishing an EPC bearer. The method for establishing an EPC bearer provided by this embodiment is a supplement to Embodiment 1, as shown in figure 2 shown.

[0072] In this embodiment, in the attachment information sent by the Internet of Things terminal, the power saving mode parameters may also include the power saving time period. During the power saving time period, the Internet of Things terminal only maintains the registration status in the network without performing communication activities. , in the present invention, the working hours of the Internet of Things terminal are alternately active hours and power-saving hours. Further, after step S105, the Internet of Things terminal enters the power-saving period after the active period, and then after the power-saving period ends, the IoT terminal enters the active period again. At this time, after step S105, the following steps are included:

[0073] Step S106, when the p...

Embodiment 3

[0083] This embodiment provides a method for establishing an EPC bearer, using an Internet of Things terminal as the execution subject, such as image 3 As shown, the method includes:

[0084] Step S201, sending attachment information to the MME.

[0085] When the IoT terminal attaches after booting, it sends attachment information to the MME. The attachment information includes: its own type information and power saving mode parameters; where the type information of the IoT terminal is used to represent the type of the IoT terminal, specifically Including fixed-position IoT terminals and mobile-position IoT terminals; power-saving mode parameters include its own active duration, which refers to the duration of a single communication activity of an IoT terminal in power-saving mode.

[0086] After receiving the attachment information, the MME judges whether the IoT terminal is a fixed-location IoT terminal according to the type information, and after judging that the IoT term...

Abstract

The invention provides an EPC bearer establishment method, and the method comprises the following steps: receiving attachment information sent by an Internet of Things terminal, and judging whether the Internet of Things terminal is an Internet of Things terminal at a fixed position or not according to type information of the Internet of Things terminal contained in the attachment information; when it is judged that the Internet of Things terminal is the Internet of Things terminal at the fixed position, controlling a service gateway and a PDN gateway to establish and store the bearing contextinformation of the Internet of Things terminal, and sending an instruction for turning off the periodic tracking area updating switch of the Internet of Things terminal to the Internet of Things terminal, so that the periodic tracking area updating switch of the Internet of Things terminal is automatically turned off after the Internet of Things terminal receives the instruction for turning off the periodic tracking area updating switch of the Internet of Things terminal; and controlling the service gateway and the PDN gateway to delete the bearing context information of the Internet of Things terminal after the active duration contained in the attachment message. The invention also provides a mobile management entity and the Internet of Things terminal. The invention relates to the technical field of communication.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to an EPC bearer establishment method, a mobility management entity and an Internet of Things terminal. Background technique [0002] The introduction of NB-IoT (Narrowband Internet of Things) technology has brought great improvements to LTE networks, that is, NB-IoT terminals (Internet of Things terminals) can work in power-saving mode, and terminals in power-saving mode, It only keeps the registration status without re-attaching or re-establishing the PDN connection, thereby reducing power consumption and extending battery life; in power-saving mode, the terminal is set with an active duration and a power-saving duration. During the active duration, the terminal can perform normal operations. During the power saving period, the terminal only remains in the registration state and is not activated. [0003] In practical applications, the terminal establishes an E...
